Pull io_uring fixes from Jens Axboe:
- Two tweaks for a recent fix: fixing a memory leak if multiple iovecs
were initially mapped but only the first was used and hence turned
into a UBUF rathan than an IOVEC iterator, and catching a case where

Pull bcachefs fixes from Kent Overstreet:
- Lots of small check/repair fixes, primarily in subvol loop and
directory structure loop (when involving snapshots).
- Fix a few 6.16 regressions: rare UAF in the foreground allocator path
when taking a transaction restart from the transaction bump
allocator, and some small fallout from the change to log the error
being corrected in the journal when repairing errors, also some
fallout from the btree node read error logging improvements.
(Alan, Bharadwaj)
- New option: journal_rewind
This lets the entire filesystem be reset to an earlier point in time.
Note that this is only a disaster recovery tool, and right now there
are major caveats to using it (discards should be disabled, in
particular), but it successfully restored the filesystem of one of
the users who was bit by the subvolume deletion bug and didn't have
backups. I'll likely be making some changes to the discard path in
the future to make this a reliable recovery tool.
- Some new btree iterator tracepoints, for tracking down some
livelock-ish behaviour we've been seeing in the main data write path.

A previous commit aborted mapping more for a non-incremental ring for
bundle peeking, but depending on where in the process this peeking
happened, it would not necessarily prevent a retry by the user. That can
create gaps in the received/read data.
Add struct buf_sel_arg->partial_map, which can pass this information
back. The networking side can then map that to internal state and use it
to gate retry as well.
Since this necessitates a new flag, change io_sr_msg->retry to a
retry_flags member, and store both the retry and partial map condition
in there.

While bdev_count_inflight is interating all cpus, if some IOs are issued
from traversed cpu and then completed from the cpu that is not traversed
yet:
cpu0
cpu1
bdev_count_inflight
//for_each_possible_cpu
// cpu0 is 0
infliht += 0
// issue a io
blk_account_io_start
// cpu0 inflight ++
cpu2
// the io is done
blk_account_io_done
// cpu2 inflight --
// cpu 1 is 0
inflight += 0
// cpu2 is -1
inflight += -1
...
In this case, the total inflight will be -1, causing lots of false
warning. Fix the problem by removing the warning.
Noted there is still a valid warning for nvme-mpath(From Yi) that is not
fixed yet.

The remove_work will proceed with permanently disconnecting on the
initial final path failure if the head shows no paths after the delay.
If a new path connects while the remove_work is pending, and if that new
path happens to disconnect before that remove_work executes, the delayed
removal should reset based on the most recent path disconnect time, but
queue_delayed_work() won't do anything if the work is already pending.
Attempt to cancel the delayed work when a new path connects, and use
mod_delayed_work() in case the remove_work remains pending anyway.

Fix a 6.16 regression from the recovery pass rework, which introduced a
bug where calling bch2_run_explicit_recovery_pass() would only return
the error code to rewind recovery for the first call that scheduled that
recovery pass.
If the error code from the first call was swallowed (because it was
called by an asynchronous codepath), subsequent calls would go "ok, this
pass is already marked as needing to run" and return 0.
Fixing this ensures that check_topology bails out to run btree_node_scan
before doing any repair.

Previously, calling bch2_btree_has_scanned_nodes() when btree node
scan hadn't actually run would erroniously return false - causing us to
think a btree was entirely gone.
This fixes a 6.16 regression from moving the scheduling of btree node
scan out of bch2_btree_lost_data() (fixing the bug where we'd schedule
it persistently in the superblock) and only scheduling it when
check_toploogy() is asking for scanned btree nodes.

syzbot reported a warning below during atm_dev_register(). [0]
Before creating a new device and procfs/sysfs for it, atm_dev_register()
looks up a duplicated device by __atm_dev_lookup(). These operations are
done under atm_dev_mutex.
However, when removing a device in atm_dev_deregister(), it releases the
mutex just after removing the device from the list that __atm_dev_lookup()
iterates over.
So, there will be a small race window where the device does not exist on
the device list but procfs/sysfs are still not removed, triggering the
splat.
Let's hold the mutex until procfs/sysfs are removed in
atm_dev_deregister().

Jakub Kicinski says:
====================
netlink: specs: enforce strict naming of properties
I got annoyed once again by the name properties in the ethtool spec
which use underscore instead of dash. I previously assumed that there
is a lot of such properties in the specs so fixing them now would
be near impossible. On a closer look, however, I only found 22
(rough grep suggests we have ~4.8k names in the specs, so bad ones
are just 0.46%).
Add a regex to the JSON schema to enforce the naming, fix the few
bad names. I was hoping we could start enforcing this from newer
families, but there's no correlation between the protocol and the
number of errors. If anything classic netlink has more recently
added specs so it has fewer errors.
The regex is just for name properties which will end up visible
to the user (in Python or YNL CLI). I left the c-name properties
alone, those don't matter as much. C codegen rewrites them, anyway.
I'm not updating the spec for genetlink-c. Looks like it has no
users, new families use genetlink, all old ones need genetlink-legacy.
If these patches are merged I will remove genetlink-c completely
in net-next.

Add a regexp to make sure all names which may end up being visible
to the user consist of lower case characters, numbers and dashes.
Underscores keep sneaking into the specs, which is not visible
in the C code but makes the Python and alike inconsistent.
Note that starting with a number is okay, as in C the full
name will include the family name.
For legacy families we can't enforce the naming in the family
name or the multicast group names, as these are part of the
binary uAPI of the kernel.
For classic netlink we need to allow capital letters in names
of struct members. TC has some structs with capitalized members.

We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

enetc_hw.h provides two versions of _enetc_rd_reg64.
One which simply calls ioread64() when available.
And another that composes the 64-bit result from ioread32() calls.
In the second case the code appears to assume that each ioread32() call
returns a little-endian value. However both the shift and logical or
used to compose the return value would not work correctly on big endian
systems if this were the case. Moreover, this is inconsistent with the
first case where the return value of ioread64() is assumed to be in host
byte order.
It appears that the correct approach is for both versions to treat the
return value of ioread*() functions as being in host byte order. And
this patch corrects the ioread32()-based version to do so.
This is a bug but would only manifest on big endian systems
that make use of the ioread32-based implementation of _enetc_rd_reg64.
While all in-tree users of this driver are little endian and
make use of the ioread64-based implementation of _enetc_rd_reg64.
Thus, no in-tree user of this driver is affected by this bug.
Flagged by Sparse.
Compile tested only.

The `name` field in `obj->externs` points into the BTF data at initial
open time. However, some functions may invalidate this after opening and
before loading (e.g. `bpf_map__set_value_size`), which results in
pointers into freed memory and undefined behavior.
The simplest solution is to simply `strdup` these strings, similar to
the `essent_name`, and free them at the same time.
In order to test this path, the `global_map_resize` BPF selftest is
modified slightly to ensure the presence of an extern, which causes this
test to fail prior to the fix. Given there isn't an obvious API or error
to test against, I opted to add this to the existing test as an aspect
of the resizing feature rather than duplicate the test.

cxl_find_rec_dram() is used to find a DRAM event record based on the
inputted attributes. Different repair_type of the inputted attributes
will check the DRAM event record in different ways.
When EDAC driver is performing a memory rank sparing, it should use
CXL_RANK_SPARING rather than CXL_BANK_SPARING as repair_type for DRAM
event record checking.
